reboot after panic: privileged instruction fault

[Spil Oss]

Hi Bjoern,

Was looking at that page, but my kernel doesn't have debug enabled.
Someone suggested getting a backtrace using the vanilla kernel, that
kernel should still be in /boot/kernel but I can't get it to fly!

/boot/kernel.old]# kgdb /boot/kernel.old/kernel /var/crash/vmcore.0
[GDB will not be able to debug user-mode threads:
/usr/lib/libthread_db.so: Undefined symbol "ps_pglobal_lookup"]

Kind regards,
